The Labour Department (LD) said it is deeply concerned about a fatal accident at a construction site in Yau Ma Tei, in which a 53-year-old worker was killed on Saturday.

Officials said the male worker was struck by a falling glass panel while it was being lifted with a set of lifting equipment.

It's understood the accident happened at a site above the Hong Kong West Kowloon Station.

"We commenced an immediate on-site investigation as soon as we were notified of the accident and issued suspension notices to the contractors concerned, suspending all curtain wall installation work of the construction site, including lifting and handling of glass panels. The contractors cannot resume the work process until the LD is satisfied that measures to abate the relevant risks have been taken," a department spokesperson said.

"We will complete the investigation as soon as possible to identify the cause of the accident, ascertain the liability of the duty holders and recommend improvement measures. We will take actions pursuant to the law if there is any violation of the work safety legislation."

The Association for the Rights of Industrial Accident Victims also said on Sunday that it is saddened and very concerned about the accident, and called on the Labour Department to be transparent with its findings.

It said it will provide the worker’s family with support and assistance.
